To all whom it may concern:

Be it known that I, JULIUS W. SNYDER, a citizen of the United States,residing at New Orleans, Orleans parish, Louisiana, have inventedcertain new and useful Improvements in Feed-Rolls, of which thefollowing is a specification.

This invention pertains to feed-rolls designed for the feeding of, forinstance, lumber in wood-working machinery in which the article to befed forward is gripped between a pair of rolls, one or both of which aredriven by power. In many cases where such feed rolls are employed, oneor both of the rolls are serrated or fluted, and, in some cases, theflutes are divided longitudinally so as to provide the roll with aplurality of circumferential series of teeth.

My invention directs itself to the building up of a roll carrying aplurality of toothed disks.

I further provide special facilities for the removal of damagedindividual toothed disks and the placing of new ones, without entirelydismantling the roll.

My invention will be readily understood from the following descriptiontaken in connection with the accompanying drawing in which Figure 1 is aside elevation of a feed-roll exemplifying my improvements: Fig. 2 aside elevation, part diamctrical section, of a portion of the improvedroll on an enlarged scale: and Fig. 3 a face view of one of the serrateddisks.

in the drawing :l, indicates the shaft of the feed-roll, this shafthaving preferably a portion of enlarged diameter between the endportions of the shaft: 2, a key-way in the enlarged portion of theshaft: 3, toothed or serrated feed-disks strung upon the enlargedportion of the shafts, these disks being preferably formed ofinterlocking halves: f, spacing disks strung upon the shaft, a spacingdisk being disposed between each pair of feed disks: 5, nuts on theshaft for clamping the disks together into a rigid structure: 6,interlocking lugs formed upon the halves of the feed disks to preventtheir separation from each other when they are in a common plane: and 7,a projection inwardly from the bore of each of the feed disks.

Feed-rolls, as a general thing, comprehend engage the key-way of theshaft and prevent the slipping of the feed disks if insufficientlyclamped. For light feeding work the projection and the cooperatingkey-way may, of course, be omitted, the friction of the clamping beingdepended upon to insure the rotation of the feed-disks.

If it becomes necessary to replace a feed disk it is only necessary toslacken one of the nuts sufliciently to permit the separation of thedisks at each side of the disk to be re moved, the degree of separationbeing equal to a trifle more than the thickness of the disk to beremoved. One of the halves of the defective disk may then be shiftedsidewise relative to the other half, whereupon both halves of the diskmay be removed from the shaft. The two halves of the substitute disk areapplied to the shaft in an obvious manner, after which the clamping nutis to be screwed up. The interlocking of the halves of the feed disksinsures the integrity of each disk when clamped in place, but for lightfeeding work the interlocking feature may be omitted and the friction ofthe clamping be depended upon to keep the halves of the disks fromseparating from the shaft. The feed dis is and the spacing disks may beformed of metal punchings, though metal is not absolutely essential forthe spacing disks. If it is convenient to remove the roll from itsworking. position, the clamping nut may be unscrewed and removed and allor a desired number of the disks removed from the shaft in order tosubstitute a new disk for a defective one. In such case the feedin gdisks need not be formed in halves.

I claim.

A feed-roll comprising a shaft, an abutment carried by the shaft nearone of its ends, a clamping nut carried by the. shaft near its otherend, a series of flat-faced spac ing-disks disposed upon the shaft, aflatsided feeding-disk formed in sections disperipheries of thefeeding-disks, combined posed between each pair of spacing-diskssubstantially as set forth. and having equal thickness throughout itsextent, and interlocking members integrally JULIUS SNYDER formed on thecontiguous edges of the sec- Witnesses:

tions of the feeding disks and having a T. J. TOMENY, J12,

thickness not exceeding the thickness of the JOSEPH J. IRWIN.
